Solid Roller Cam

Is there any other benifits other then higher reving if I were to go to a Solid Roller. What are the major downfalls that have kept others form doing this ?

upside: faster ramps which increase the area under the curve without increasing duration. Can use stronger springs to hold off valve float. Lighter components which also helps hold off float.

Downside: requires periodic adjustment. Noisier valvetrain. can put more stress on the valve train particularly cams, pushrods and valve springs which could be an issue for a street car.

A solid roller will make more power...no doubt. However, as Ralph alluded, solid rollers don't last. They wear out in ~25-35k miles. The added load on the camshaft, the lifters, the pushrods, and the rocker arms just wears out the valvetrain. If you're building a track motor, go for it. If you're building a street motor, stick with the hydraulic roller.

I plan to build my engine on an old block so I don't have a choice if I don't want to spend all that money on a retrofit hydraulic roller. should I go with solid roller or non roller for a street car? Is it worth to live with the downsides with a solid roller? :cheers:

Sorry for hijacking, but I figured that the topic is the same... :blueangel:

check on the SpeedDemonMotorsports website, if I remember correctly they had some good info comparing solid roller cams to hydraulic

Re: Solid Roller Cam (keekster)

I had about 15k miles on my solid roller in my 396 when I pulled it out back in December...It still checks fine. But, as others have already said, it does require more periodic maintenance. I checked/ran my valves every other oil change (I change about every 2500 miles). For most people who would run a solid roller though the mileage isn't a factor; I don't know anyone running a solid roller on the street that won't, for some reason or other, pull his motor down long before 25k miles!!!
